How to Get Rid of Fever Blisters

Fever blisters, also known as cold sores, are caused by the herpes simplex type 1 virus. An outbreak usually occurs on or around the mouth and typically heals within two to three weeks.

Fever blisters can be a lifelong irritant, since the virus remains dormant in the body throughout your life. Outbreaks can be triggered by stress, overexposure to sunlight, hormonal changes, trauma to the skin, or a weakened immune system.

Fever blisters are painful, accompanied by tingling and burning sensations along with swelling and inflammation. They appear as a cluster of small, white blisters and typically manifest on the same spot or area whenever the virus gets activated. Getting fever blisters can be a real pain and can even spoil your beauty.

There are many over-the-counter medicines for fever blisters, but they are not always effective and can take a lot of time. Instead, you can try some simple, natural home remedies that can help provide relief in just four to five days.

For best results, use these remedies as soon as you notice the initial tingling sensation. It will help reduce the duration and severity of an outbreak.

how to get rid of fever blisters

Here are the top 10 home remedies to get rid of fever blisters.

1. Tea Tree Oil

Tea tree oil can quickly and effectively treat fever blisters due to its antiviral properties.

  • Dilute tea tree oil by combining one part oil and three parts water. Using a cotton ball, apply the diluted tea tree oil on the affected area three times a day. Within a few days, the fever blister should heal completely.
  • Alternatively, mix equal amounts of tea tree oil and olive oil. Add a little bit of eucalyptus oil. Apply this solution on the blister three times daily for four to five days.

2. Whole Milk

Another very simple treatment for fever blisters is whole milk. Whole milk contains immunoglobulins and calcium, which help fight the virus that causes fever blisters. Plus, it has a type of fat known as monocaprin with antiviral properties. Milk also helps accelerate the healing process.

  • Soak a cotton ball in cold whole milk and apply the milk on the affected area. Leave it on for about 10 minutes. The cold milk will reduce the pain as well as soothe the tingling sensation. Do this several times a day for three to four days.
  • Also, drink a glass of warm whole milk with one teaspoon of turmeric in it two times a day for a week. Turmeric will help reduce the pain associated with fever blisters.

3. Hydrogen Peroxide

Hydrogen peroxide is a natural disinfection and hence very effective in killing bacteria that may infect the fever blisters. The herpes virus that causes fever blisters thrive in moist, warm environments; using hydrogen peroxide will keep the affected area dry and free of moisture.

  • Dip a cotton ball in 3% hydrogen peroxide solution and dab it over the blisters. Leave it on for a few minutes and then rinse the area with a wet washcloth and pat dry. Repeat this remedy three or four times a day for two to three days.
  • Alternatively, make a paste of two crushed aspirins and one teaspoon of 3% hydrogen peroxide. Apply the paste on the affected area using a cotton ball. Leave it on for just two to three minutes. Clean the area with lukewarm water. Do this once daily for not more than two days.

4. Ice

Cold compresses can alleviate pain significantly, as well as reduce the swelling and redness associated with fever blisters. It will also prevent the condition from spreading.

  1. Wrap a few ice cubes in a washcloth.
  2. Place it over the affected area for 10 to 15 minutes.
  3. Repeat this every three to four hours.
  4. After each session, apply a thick layer of lemon balm ointment to the area.

This remedy works best when used as soon as you feel the initial tenderness or a tingling sensation on your lip, which usually happens during the first few hours or a couple of days before the blisters develop.

5. Garlic

Garlic is one of those ingredients that you can rely upon when you want to get rid of fever blisters as fast as possible. Garlic has enzymes that work as antiviral agents that help treat fever blisters. Plus, its antibacterial properties will help disinfect the area and decrease the healing time.

  1. Gently crush two to three garlic cloves to make a paste.
  2. Apply it to your fever blisters.
  3. Leave it on for 10 to 15 minutes.
  4. Repeat the process three times a day for two days.

Warning: Garlic is potent and may sting a bit when applied.

6. Licorice

Licorice has an active ingredient called glycyrrhizin that has antiviral and anti-inflammatory properties that make this herb an effective treatment for fever blisters. It will minimize redness and swelling and also speed up the healing process.

  • Make a thick paste of one tablespoon of licorice root powder and one-half teaspoon of water. Dab the paste on the affected area using a cotton swab. Leave it on for a few hours. Reapply it three to four times a day for several days until the blisters heal completely.
  • You can also drink licorice root tea or take supplements to speed up the healing process.

Note: Those who have high blood pressure should avoid licorice remedies.




  1. Its all about the tea tree oil. Seriously. From what I’ve seen with people it works the best by far out of all the options out there.

    • Actually I did all kinds of remedies from the toothpaste to the salt and to the baking soda and even tea bags it’s all effective actually but it’s a but slower than a tea tree oil I just dump a little with a cottonbuds then after awhile it dries out. TEA TREE OIL IS THE BEST if u want the healing fast :)

  5. I tried this last week, and it worked!! Take a used and cooled damp teabag and hold it gently on the cold sore for a minute or so, two or three times a day for two or maybe three days and that should do the trick. It’s not much bother. Give it a go. Good luck!!

  10. Am about to try these remedies.

  11. Buttermilk applied before bedtime. I remember my aunt telling me this when I was younger and when I woke up it was gone. It was smelly, and it stung, but it worked!

  12. Sometimes I use rubbing alcohol and it works. Also the white toothpaste before bed works great. I’m gonna try a few of these ones and if anything works out I’ll update. Good luck…these are a nightmare.

  13. Hey guys, ever try putting peppermint oil on a q-tip. It takes the heat right out of the cold sore/fever blister. I get them alot from lack of sleep due to miserable restless legs:(

  14. Hey.. I’ve dealt with fever blisters n cold sores LITERALLY MY ENTIRE LIFE… off and on… Sometimes it be years of not getting them and then boom one day I’ll wake up to a heavy top or bottom lip….. Lol… Anyhoo… Last month I was devastated with two…. Then of course now this month im on my fourth one in two months. Every time I get one under control damn near invisible I get another one.. Smh… Im sick of them…. I don’t know what else to do….. And no I don’t have herpes…just on of them people who unfortunately gets them.. And it not fun.. Or pretty…. Smh.. I have I one now it hurts so bad I don’t even want to touch it.. I’ll try a few of these remedies.. Hopefully they work for me too.. Thanks…

    • This happens to me to I have always gotten these my whole life…. But I am young and I hope I can get a handle one them me and my mom always struggle with them….. Try tea tree oil it works good… Wish I could get them to go a way faster I always get stared at in school… Any way I need help with this this site has done me good

      • Pop the blisters…sqeeze out liquid
        Make a paste of vicks vapor rub
        And meat tenderizer….seriously
        It will dry up overnight

        • Squeezing them makes them worse a lot worse. I know decolorized iodine works good. In most cases they never come up. As long as you catch them ASAP like at the itching. I have one now bit it started while I was at work. But I do know squeezing is the wrong thing to do

  15. I woke up with a fever blister Wednesday morning. Each day it grew bigger and more painful. Not only did the fever blister get bigger, my lip was swollen, the side of my face was swollen and painful to the touch. I used some sort of ointment but it was not working. Lately I have moved to using more natural ways of healing myself. I found this website and bought myself some tea tree oil. I mixed with a part tea tree oil and part olive oil. I did not have any eucalyptus oil so I left that out. I started applying the mixture about 4-hours ago and have made 3-applications so far. It works..!! It works…!! It works…! The swelling has gone down, my lip has deflated, the pain in the side of my face is gone and I have only used it for the last 4-hours. I will be using this for some other stuff on my body as well. I will updated in a few days. I hope that the blister will be completely gone…!! Loved it..!!

  16. I totally love this site and already the fever blister is starting to go away

  17. Also toothpaste/salt work too mix together to make a paste and then apply to fever blister/coldsore let it sit for about 10 to 15 minutes and do this for 24 hours 2 times

  18. This is an excellent site. Oodles of good, tried and true, information. Thanks for sharing with us.

  19. Yes it’s very pain makes you not want to do anything but I’m going to try one of theses remedies

  20. The ice really works

  21. I numb my lip with the ice, and then do the garlic. When my lip is numb I don’t get the stinging effects of the garlic

  22. I don’t know about y’all, but I’m going to take a tea bag stick it in ice, add peroxide, add a dab of tea tree oil, toothpaste, aloe.. stick it to my lip and eat some yogurt followed with whole milk and a licorice stick. All at once! Lol

  23. This site is the best I’ve found! I tried hydrogen peroxide and vanilla on Q-tips before going to bed and it was dried up in the morning. Fastest relief I’ve found. Thank you, thank you, thank you!!!

  24. I went to work with no fever blister and by the time I got off I had a very small bump. At first it didn’t tingle or itch, but I hurried to the store to get the top name brand you see on TV. I paid almost $20 for it and started putting it on every few hours. When I woke up the next morning it was a big ugly painful Klondike I was so embarrassed I didn’t want to go to work…so I found this site and boy am I glad… I tried the peroxide and the peroxide paste with the 2 aspirins….worked wonders took all the swelling down, all the fever and stuff that was in the blister disappeared and was the blister was smaller within a few hours. What’s so great about it, I already had this at home. I used the peroxide in a spray bottle to keep my lip clean and sterile. Plus I did try the peppermint oil and the tea tree oil both worked well also…also had these two products at home. I have a scab now and can’t wait until it heals and comes off …so tempted to try to take it off but I will give it a couple more days. I will stick with the peroxide for my next episode. It works for me. The best treatment I have ever had in my entire life. I use to suffer for 7-10 days using crap that didn’t work just make the blister soft and no healing properties…I paid good money for nothing. 2 days of using this for me and I am on the road to a speedier healing process…I wish I could get a refund on this bunk product I bought. Thanks for the tips….printing them out so I can have them on hand in case someone I know might need some alternatives to expensive store bought remedies, when home remedies might be all you need.

  25. I just broke out with 2 blisters on my lip. It is very painful, but thanks to this website I have some relief. I applied
    tea tree oil. Wow feels better instantly. Hopefully they heal soon.

  26. I have prom tomorrow April 10th 2015 and I have this annoying blister on my bottom lip! :( I can’t get it to go away fast enough before tomorrow and before I have my makeup done my professionals

  27. Lysine works wonders. It’s a daily supplement you take and you shouldn’t get them or, if you do they won’t be as horrible. If I do feel one coming up I simply start doubling up on lysine taking 2-4 p/day instead of the usual 1or 2 and it shuts it down and stops it from getting worse. I have 2 yucky ones coming up now becuz I keep forgetting to get more lysine so OFF to the store I go!
